Yosemite successfully installed, no issues.

[Spewed 0]

Last night, I decided to install Mavericks on my computer. Realized I wouldn't have Internet connection so it would be virtually pointless to have it on my PC at the moment. So today, I decided Mavericks was just a practice run, for what I wanted which is Yosemite. Today, i Iinstalled Yosemite before I went to work. Took about 30 minutes, I literally ran into zero issues. When installing Mavericks it seemed to be issue after issue after issue. Everything went swell. 
Now just waiting to purchase a compatible network card.

Hello answering to your new plans to buy:

 

I have 2 different ways to connect... tried in Yosemite:

 

ASUS WLAN USB N13 (B1)[Chipset RTL8192CU] Didn't worked so well even with the latest drivers from Realtek, disconects sometimes but works... (On mavericks perfect...)

TP-Link 300mbps 851-ND(wifi)With some kexts i found... Doesent show any networks but its reconogised... (On Mavericks works perfect full connection, any issues)

 

I hope this can help you
